摘要:
An apparatus for surface finishing includes a robot and an end effector. The end effector includes a compliance wrist having an axis of movement and coupled to the robot and a grinder tool coupled to the compliance wrist. The robot is configured to controllably position the end effector in three-dimensional space. The compliance wrist is configured to bias the grinder tool to a biased position relative to the robot and enable the grinder tool to move relative to the robot in response to an external force acting upon the grinder tool.

An air circulation system for vocal music and band ensembles provides a downdraft through a riser structure to remove aerosols from around performers in the riser structure. The riser structure includes platforms and an air intake disposed within a vertical space between the platforms. The aerosols are drawn through the riser structure, cleaned, and filtered and exhausted away from the performers.

Embodiments of the present invention relate to an adapter that fits over a wheel barrow handle that is extendable. By way of this extension, the height of a handle portion of the adapter may be changed so as to change the effective height of the wheel barrow handle. In this way, a user of the wheel barrow can lift the wheel barrow from a more comfortable height.

The present invention is used in an emergency network to identify and provide the correct public safety access point (PSAP) to service an emergency call originating from a Voice Over Internet Protocol (VoIP) subscriber. Data stores in an emergency services network associate PSAPs to an input ZIP code obtained from a street address returned from an MSAG relating to a VoIP call, and PSAPs to an input ESN. An emergency caller's civic street address is matched against a nationwide MSAG data store to result in a MSAG ESN. From the street address, the emergency caller's ZIP code is matched to a PSAP in an appropriate ZIP/PSAP data store. A matching PSAP from both the ZIP/PSAP and PSAP/ESN data stores determines with great reliability the identity of the proper PSAP for that emergency caller.

An apparatus for subjecting fluid moving through a fluid delivery line to a magnetic field is provided. The apparatus comprises a plurality of magnets, magnet holders, and encapsulating structures, which together increase the magnetic force capable of being applied to the fluid delivery line due to the properties of the encapsulating structures and, preferably, the magnet holders. The apparatus also contains a novel tabbed magnet holder such that individual magnets may be easily removed and replaced to provide magnetic fields with differing properties, such as a much stronger or weaker field or a field capable of imparting spin upon the fluid.

An apparatus for surface finishing a flange surface of a flange of a pipe includes a frame assembly, a drive assembly coupled to the frame assembly, and a bracket assembly coupled to the frame assembly. The flange is clamped between the frame assembly and the drive assembly. The drive assembly circumferentially translates the apparatus around the pipe. A power tool is coupled to the bracket assembly to perform the surface finishing operation on the flange surface of the flange.
